<span>7 - 4[3 - (4y - 5)]
= 7 - 4[3 - 4y + 5]
= 7 - 4[-4y + 3 + 5]
= 7 - 4[-4y + 8]
= 7 + 4*4y - 4*8
= 7 + 16y - 32
= 16y - 32 + 7
= 16y - 25</span>

Please help work this out
BigorU [14]

Answer:

Area=190.091 cm^2

Step-by-step explanation:

Area = 1/2(Pi x r^2)    one-half because it's a semi-circle

Area=1/2(3.14 x 11^2)

11^2=121 so, Area=1/2(3.14 x 121)

Area=1/2(379.94)

Area=189.97 cm^2

adjustment:

Area=1/2(3.142 x 11^2)

Area=1/2(3.142 x 121)

Area=1/2(380.182)

Area=190.091
